- OXYGEN-GENEBTOE.

To all 'whom it ma/y concern:

Be itknown that I, NEWTONAJ. ANDERSON, a citizen of the United States of America, residing at Coffeyville, in the lcounty of Montgomery and State of Kansas, have invented certain new and useful Improvements in Oxygen-Generators, `ot' which'the following isa specification, reference being had therein to the accompanying drawing.

ThisV invention relates to the subject of producing gaseous fuels for use in connection withwelding and other tools, and the principal object of the saine is to provide ya `producing plant in which oxygen can be cheaply, rapidly and safely generated and delivered to a Welding or other tool to be mixed with gas and thereby form the heating fuel for the tool,

In carrying out the objects of the invention generally stated above, it will be understood, of course, that the essential .teatures of the same are necessarily susceptible of changes in details and structural arrangements, one preferred and practical embodiment` of which is shown in the accompanying drawings, wherein v Figure 1 is a view in en'delevatijon of a portion of the oxygen producing retort. F ig. 2 is a similar side elevation partly in section-fof the retort. Figs. S and 4 are respectively transverse andflongit-iuiinal sectional views of a check valve ,used in connection with the piping from the retort. Figs. 5 and G are views respectively of the top and bottom of a washer used in connection herewith, the views being at rightangles to cach other.

The improved generating plant is of special utility in the production of oxygen 4or use in connection with the type of Welding torches which forms the subject-matter ot' Letters Patent of the United States No.` 976,71? granted to me November 22, 1910.

The oxygen generator comprises a cylindrical retort 7 that is horizontally supported inthe concaved seats 8 carried by the arched legs 9 which have their fiat bases l0 rigidly fastened to the platform 11. Tie bars 12 encircle the retort 7 and rigidly fasten the same to theseats 8. Transverse bars 12a connect the legs 9 and serve as supper s to retain the burners 13, or other source of heat, beneath the retort "1' A hood 13 incloses the retort and the sourceV of heat in spaced relation and is provided with'upper openings 14 for the escape of the products ,forced central end of the .casing 'Specification of Letters Patent.

of combustion. The rear end of the retort is externally threaded and an intel-nali". threaded flanged cap 15 is employed for sealing said rear end. The forward end of the retort 7 has its edge provided with longitudinally-extending threaded openings 16 which are engaged by the bolts 17 that pass through the flange 18,'of a cover plate 19 to cause said plate to seal the forward end of the retort. A gasket 20 is interposed be tween the flange 18 and the forward end of the retort. Retort 7 is provided .with a discharge pipe 21 that, is fitted gas-tight in its upper portion. Pipe 21 projects through and above hood 13 and its upper end is suit'- ably coupled to a connect-ing pipe 22 which is in turn coupled to the inlet pipe Q3 that enters a washing tank 2% through the top thereof. Tank 24 is preferably cylindrical and the discharge pipe 25 of tank Q4 is suitably coupled to a connecting pipe 26 which in turn is coupled te a suitable storage tank or like receptacle not deemed necessary here The pipe 21 is preferably equipped with a check valve fonpreventing back-flow of the gas. The type of valve employed is shown in detail in Figs. 5 and G, and by referring thereto it will be seen that said .valve cornprises a casing 36 provided with a central, transversely-armnged perforated partition' 37. Said partition is provided with a reinportion 88 having a guide opening 39 formed through it. A valve stem 40 is slidabiethrough opening 39 and carries a disk, or other type of valve 41 adapted to enga e a seat'tQ in the 'inlet end of casing sprin 43 is coiled about stem 40, one end thereot bearing against the l valve L11, and the other end bearing against the center ot the partition 37. As will be obvious, the tension of spring til is being constantly exerted to retain the valve 41 on its seat 42, but the pressure pf the incoming oxygen is sutlicient to overcome the tension of spring 43 so that the valve is retained open and the oxygen {kms-through the easing 36. In the event of a backlow of the oxygen, it will be clear that said valve willA be quickly seated and thereby seal the inlet 36. i' Washer tank 24 is provided with a lower clean-out opening 44 rom which a discharge tube 45 rejects. A controlling valve tt is provided) for the tube 45. Tank 24 alsii provided with an upper opening 47 from (it)v which a filling tube 48 projects, said tube being provide with a controlling valve 49 and a seat 50 for a funnel 51. .Y

, It should be understood that the check valve which I have illustrated in Figs. 3 and 4 is merely a conventional form of a, check valve and that an check valve may be use in place thereof,

threaded openings, a sealing plate for said `end of the retort provided with a flange,

bolts engaging the said flange and openings other convenientl to lock said plate over said end of the retort, means for heating said retort, and a hood. inclosin said retort and heating means and provide with openings for the escape of products of combustion.

2. A gas producer comprising a horizontally arranged cylindrical retort, supporting legs provided with concaved seats for said retort, clamping bars for locking said retort to said seat, means for heating said retort, and a hood covering said retort provided with escape openings for the products of combustion.

In testimony whereof I hereunto aiiix my signature in resence of'two witnesses.
